ADAM EIDAM, OF HAZLETON, PENNSYLVANIA, ASSIGNOB OF ONE-HALF TO GEORGE w. WILMOT, OF HAZLETON, PENNSYLVANIA.

CARBURETER ATTACHMENT.

Application filed November 27, 1917.

To all whom it may concern Be it known that I, ADAM Ewan, a citizen of the United States. residing in Hazleton, county of Luzerne, State of Pennsylvania, have invented certain new and useful Improvements in (arhureter Attachments. of which the following is a specification.

My invention relates to a gaseous fluid mixing attachment adapted to be interposed in the pipe leading from a carburetor to the manifold through which the fluid fuel supply is delivered to an explosive engine.

It has for an object to provide means for admitting air into the said pipe and causing it to comingle and mix thoroughly with the inflammable mixture delivered from the carbureter.

A further object of my attachment is to effect, as I term it, a refining of the mixture so that greater power and efiiciency may be derived therefrom.

I have found in practice that when an attachment embodying my invention is employed in the manner above indicated a substantial increase in power is derived, without regard to whether the engine is operating at its highest speed and power or at its lowest speed and power.

In order that my invention may be more readily understood and its practical and commercial advantages fully appreciated reference may be had to the accompanying drawing in which I have illustrated one form of a convenient embodiment thereof. It will be understood, however. that changes in the details of construction may be made within the scope of the claims without departing from my invention.

In the drawing:

Figure 1 is a view in edge elevation of a de ice embodying my invention, said device being in position in the pipe leading from the carburetor to the manifold. the carbureter and said pipe being also shown in elevation:

Fig. 2 is a top plan view of the said attachment with a portion thereof broken away to show a detail of construction: and

Fig. 3 is a transverse sectional view taken on the line 33 of Fig. 2.

Referring to the drawing. 1 designates a carburetor and 2 a pipe leading therefrom to the manifold for supplying gaseous fuel Specification of Letters Patent.

to an explosive engine. The pipe 2 is not continuous but consists of two parts, each part being provided with a flange 3 as shown. The attachment embodyin my invention, indicated as a whole by the reference numeral +1, is interposed between the opposing ends of the two portions or sections of the pipe 2 and is secured between the flanges 3 by means of bolts 5 which extend through the said flanges and through open ended slots 6 in oppositely disposed ends of the body of the attachment 4.

The said attachment 4 comprises a disklike member 10 of suitable material, as aluminum, provided with a central opening 11 to register with the opening or passage through the pipe 2.

The said disk-like member 10 is provided at its opposite sides with relatively deep slots 12, the outer sides of which are closed by means of wire-gauze screens 13 and narrow plates 14. The said plates and gauze screens are provided with openings at their opposite ends through which screws 15 extend, which screws engage openings 16 in the projecting lug-like portions 17, formed by extending and undercutting the opposite ends of the slots 12. The central portions of the plates 14 are cut away or slotted. as indicated at 18, in order to permit air to flow freely through the auze screens 13 into the chambers forme between the said screens and the bottoms of the slots or grooves 12. The presence of the plates helps to secure and hold the gauze screens in position and also protect the latter.

In order that air may be delivered from the chambers formed by the slots 12 I have provided small tubes 19 and 20 which cross each other. as shown. substantially at right angles,-although the angle at which they cross may be varied or. changed without departing from my invention.

These tubes terminate at the bottoms of the chambers or slots 12 as shown. The said tubes are provided with perforations 21 which extend only partway therethrough. the said perforations facing toward the engine; that is to say. away from the carburefer.

It is apparent that air entering through the gauze screens 13 into the chambers 12 is delivered therefrom through the tubes 19 and 20 into the pipe 2. The perforations 21 are situated at intervals along the said tubes so that the air is discharged from the said tubes in a greater or less number (9 in the construction shown) of small streams. These streams of air being projected or discharged into the pipe 2 at different points distant from the inside surface of the pipe 2, the air is mixed thoroughly with the gaseous mixture coming from the carburetor and there is no tendency for the air thus introduced to hug and stay close to the inside surface of the said pipe. The amount of air delivered through the perforations 21 from the tubes 19 and 20 is proportionate to the vacuum created in the pipe 2 by the operation of the engine. It is apparent, therefore, that the amount of air varies with the speed and power at which the engine is being operated so that air is always introduced in the proper proportions to produce a gaseous mixture in which the air is proportioned to the other gaseous elements eutering into the mixture that a resultant very efficient mixture is produced.

By providing the disk-like member 10 with the slots 12 therein to form the chambers as described I reduce to a large extent the quantity of material necessary for the. construction of the disks and furthermore provide means whereby the air which is delivered through the tubes 19 and 20 is strained so as to remove therefrom dirt and other objectionable substances which might otherwise enter the said tubes.

1 claim 1. As an article of manufacture, a gaseous fuel mixing device comprising a member having a central opening therethrough and being adapted to be interposed in a conduit leading from a carbureter to a gas engine, said member having slots in the outer edge thereof, tubes extending across the said central opening and terminating at their opposite ends in the said slots and means for covering the outer sides of said slots to remove foreign substances from the air which may enter the opposite ends of the said tubes.

2. As an article of manufacture, a gaseous fuel mixing device comprising a disklike member having a central opening there through, said member being adapted tov be interposed in a pipe leading from a carbureter to a gas engine, said disk-like member having chambers formed in opposite edges thereof, gauze screens for covering the outer sides of said chambers and tubes extending across said opening, the opposite ends of said tubes terminating in the said chambers.

As an article of manufacture, a gaseous fuel mixing crevice, comprising a dislclike member having a central opening therethrough, said opening being adapted to be interposed in a pipe leading from a carbureter to a gas engine, said disk-like member h .ving chambers formed in opposite edges thereof and being provided with projecting parts which extend over opposite end portions of the said chambers, gauze screens for covering the outer sides of the said chamber, said screens being secured to the said projecting parts, and tubes extending across said opening, the opposite ends of said tubes terminating in the said chambers, and the said tubes being provided with a plurality of perforations therein.

4. As an article of manufacture, a gaseous fuel mixing device, comprising an oblong relatively thin flat member having a central opening therethrough, said member being adapted to be interposed in a pipe leadin from a carbureter to a gas engine, said member having chambers formed in opposite sine edges thereof, and being provided with open ended slots in its opposite ends by means of which it may be detachably held in position between opposing ends of said pipe, gauze screens for covering the outer sides of said chambers, and tubes extending across said opening, the opposite ends of said tubes terminating in the said chambers, substantially as described.

In testimony that I claim the foregoing as my invention, 1 have hereunto signed my name this 22nd day of November, A. D. 191(.
